STOVE-BOARD.

SPECIFICATION forming part of Letters Patent No. 233,165, dated October 12, 1880.

Application filed May 14, 1880. (No model.)

To all whom it may concern Be it known that I, HERMANN RENDTORFF, of Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Stove-Boards, of which the following is a specification.

The object I have in view is to so improve the crystallized-tin stove-board patented October 15, 1878, by A. (J. Stoessiger, that the same will be much cheaper and stronger in construction. can be packed in less space for transportation withoutdanger of beinginj ured, and will be more convenient in use.

My invention consists in the peculiar construction of the improved crystallized-tin stoveboard, as fully hereinafter explained, and pointed out by the claims.

In the accompanying drawings, forming a part hereof, Figure 1 is a top view of the round stove-board 5 Fig. 2, a section of a portion of the same on line y y, and Fig. 3 a sectional perspective view of the edge of such round board,

The stove -board is made rectangular in shape orof circular form. For convenience of illustration the circular board is alone shown in the drawings. The rectangular board is the same in construction as the circular board, with the exceptions that in the rectangular board the sections of crystallized tin are, of course, cut to fit the shape of the board. The crystallized tiu does not have to be crimped or corrugated at the edges, because such edges are straight and not curved, and the coriiers of the board are provided with metallic finishing-caps.

The base of the stove-board is composed of two layers of thin wood boards, A B, laid across each other to prevent warping and nailed together, the boards of one layer running at right angles to those of the other layer. This base extends throughout every portion of the board. The base is covered by a top, 0, of crystallized tin, made in sections a b c d, preferably four in number, and connected on lines radiating from the center of the board by rigid sheet-metal seams or joints 0, Fig. 2.

In the circular board the edges of the tin covering are crimpe l down, covering the edges of the base and projecting under the same.

In the rectangular board the crystallized tin is bent under the wood base, and at the corners the board is covered by metal caps.

At the center of both forms of board, where the inner corners of the sections a b c d meet, the space left is covered by a finishing-plate, f, secured by a tack driven into the wood base. The tin before being secured upon the board is crystallized in the well-known way, and is then ornamented in colors by lines or figures, or both, painted thereon, after which the crystallized and ornamented tin is covered with a transparent fireproof varnish, which is baked upon the tin at a high temperature, and forms a hard glazed surface that will not crack off, and is water and fire proof. This board is cheaper than that heretofore made of crystallized tin, and is cheaper to construct, pack, and transport; is stronger, more durable, and more convenient than the stove-board shown in the patent of Stoessiger, before referred to.

As a modification of the manner of securing the tin top to the wood base the tin may extend only to the edge of the base and be covered at its edge and secured by a separate band pressed or spun from sheet metal in any ornamental shape. Such band wouldlap over the edge of the tin top, would cover the edge of the wood-base and would be secured to such wood base in any suitable manner.

What I claim as my invention isl. The stove-board described, consisting of wood base A B, extending throughout the board, the crystallized-tin top 0, made in sections at b c d, secured together on lines radiating from the center of the board by rigid sheet-metaljoints c, and the finishing-platef, covering the inner corners of the sections and the inner ends of the joints 6, substantially as set forth and shown.

2. A stove-board having a wood base and a top of crystallized tin made in sections, socured together by rigid joints e, and bent over the edge of the wood base, substantially as described and shown.

HERMANN RENDTORFF.
